RUNNER FOR GRAIN-DRILLS.

SPECIFICATION forming part of Letters Patent No. 386,911, dated July 31,1888;

Application filed June 15, 1887.

To all whom it may concern:

Be itknown that I, JOHN L. ASHURST, a citizen of the United States,residing at Havana, in the county of Mason and State of Illinois, haveinvented a certain new and useful Improvement in Runners forGrain-Drills; and I do hereby declare that the following isafull, clear,and exact description of the same, reference being bad to the annexeddrawings, making a part of this specification, and to the letters andfigures of reference marked thereon.

This invention relates to an improvement in runners for cornplanters ofthat class which are designed to open the earth to each side and give aplane surface to the bottom of the furrow, and at the same time to forma secondary furrow narrower than the first; and the object of theinvention is to improve upon and cheapen this class of devices, to whichends the invention consists in the peculiar construction of the runner,as hereinafter more fully described, shown in the drawings, and thenspecifically defined by the claim.

My invention is clearly illustrated in the accompanying drawings, whichform a part of this specification, and in which Figure l is aperspective view of my improved runner, and Fig. 2 is a rear elevationthereof.

Referring to the drawings by letter, A designates the runner formed of asingle piece of metal, preferably of steel, having its front brought toa thin edge, as is usual in this class of instruments. From the point adiverge the wings B B, which are cut away at b to form the secondarywings O G, which latter wings, owing to the divergence of the wings B,are not so far apart as the wings B B; consequently, as the runner isdrawn forward the wings G will form a narrow furrow, which constitutesthe seed-bed, and the wings B form a wider furrow upon a higher plane:At a may be attached, in any suitable way, the ordinary Serial No.241.395. (No model.)

shank or boot (not shown) for conveying the seed to the seed-bed.

In devices of this kind as heretofore constructed no provision has beenmade for the pressing down or evening of the sides of the upper furrow;consequently, in operation the wings which form said upper furrow forcethe dirt over onto the next preceding furrow, thus covering the seedunevenly and leaving an uneven ridge between the furrows. To avoid this,the upper extreme ends of my wings B are bent slightly outward and over,as shown at c.

In operation, as the runner is drawn forward through the ground thewings 0 form the narrow furrow or seed-bed, and at the same time thewings B form the wider furrow, and as the earth is thrown aside by thesaid wings B the bent-overportious 0 thereof tend to press down upon theloosened earth, and serve to prevent the same from being thrown overonto the next furrow. I thus insure an even shallow covering of the seedand an even regular ridge between each two furrows, which is a greatprotection to the plants.

Having thus described my invention, and set forth its merits, what Iclaim as new, and desire to secure by Letters Patent, is

As an improved article of manufacture, the runner described, formed of asingle piece of metal wedge-shaped, as shown, and cut away at the heel,as at b, to form wings B B and G 0 upon different horizontal planes, andthe rear upper corners of the wings B bent outwardly and over, as at a.substantially as and for the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JOHN L. ASHURS'I.
